Participants

Reaction Steps

To a solution of 4a (7.75 g, 26.7 mmol) and 1,3-propanedithiol (3.03 g, 28.1 mmol) in 50 mL acetic acid was added boron trifluoride etherate (7.98 g, 56.2 mmol). The solution was stirred overnight, diluted with ether, washed with H2O, saturated NaHC3, and brine and dried (MgSO4). Removal of the volatile in vacuo provided a residue which was crystallized from hexane, wt 8.0 g, mp 100°-101° C. Anal. C20H25FO2S2 : Theory C: 63.12; H:6.62; S:16.85. Found C: 63.45; H:6.58; S: 16.44.
